16.69 Ct. Brown Smoky Quartz from Brazil

This listing describes a single natural brown smoky quartz, transparent in body, weighing 16.69 carat, with an oval outline and finished as a faceted gem. The dimensions are 22.28 x 16.10 x 8.82 mm, the cutting style is mixed brilliant, and the overall presentation reflects an excellent polish. Clarity is graded as eye clean under standard viewing at eye level, and color falls within a dark intensity range that gives the stone a deep, consistent tone without masking its internal clarity. The specimen is natural, with no enhancement, and the documented origin is Brazil. The Natural Gemstone Company provides this information to support appraisal, setting design, and provenance requirements for both individual collectors and professional jewelers.

Optically the gem displays the balanced interaction of tone and facet architecture characteristic of a well executed mixed brilliant cut on quartz, with a broad table and pavilion passages that channel light through the stone and return a restrained but perceptible scintillation. The dark brown hue reads as sophisticated and stable in variable lighting, maintaining depth in lower light and revealing warmth in brighter illumination. The eye clean clarity permits unobstructed appreciation of the cut and color, and the excellent polish maximizes surface luster while ensuring crisp facet junctions. As a quartz specimen the material offers a reliable combination of hardness and workability, with a Mohs hardness that affords everyday wearability when set appropriately in secure mounting styles.

The dimensions and oval shape make the piece particularly versatile for a range of jewelry applications, including a prominent center stone for a cocktail ring, an elegant pendant, or an ornamental element in a cufflink or brooch. The dark brown tone offers compatibility with multiple metal choices, creating contrasting or harmonious palettes with yellow gold, rose gold, white gold, and sterling silver. In formal contexts the stone provides an understated focal point that supports accent diamonds or lighter colored gems without competing for attention. In casual settings the stone serves as an approachable, durable centerpiece that pairs well with textured metals, leather, and mixed material designs. The mixed brilliant cut contributes to balanced return of light, which allows the stone to read consistently in both indoor and outdoor environments.
